Population Assessment of Tobacco and Health (PATH) Study [United States] Master Linkage Files

The PATH Study was launched in 2011 to inform the Food and Drug Administration's regulatory activities under the Family Smoking Prevention and Tobacco Control Act (TCA). The PATH Study is a collaboration between the National Institute on Drug Abuse (NIDA), National Institutes of Health (NIH), and the Center for Tobacco Products (CTP), Food and Drug Administration (FDA). The study sampled over 150,000 mailing addresses across the United States to create a national sample of tobacco users and non-users. 45,971 adults and youth constitute the first (baseline) wave, Wave 1, of data collected by this longitudinal cohort study. These 45,971 adults and youth along with 7,207 "shadow youth" (youth ages 9 to 11 sampled at Wave 1) make up the 53,178 participants that constitute the Wave 1 Cohort. Respondents are asked to complete an interview at each follow-up wave. Youth who turn 18 by the current wave of data collection are considered "aged-up adults" and are invited to complete the Adult Interview. Additionally, "shadow youth" are considered "aged-up youth" upon turning 12 years old, when they are asked to complete an interview after parental consent. At Wave 4, a probability sample of 14,098 adults, youth, and shadow youth ages 10 to 11 was selected from the civilian, noninstitutionalized population at the time of Wave 4. This sample was recruited from residential addresses not selected for Wave 1 in the same sampled PSUs and segments using similar within-household sampling procedures. This "replenishment sample" was combined for estimation and analysis purposes with Wave 4 adult and youth respondents from the Wave 1 Cohort who were in the civilian, noninstitutionalized population at the time of Wave 4. This combined set of Wave 4 participants, 52,731 participants in total, forms the Wave 4 Cohort. Please refer to the Restricted-Use Files User Guide that provides further details about children designated as "shadow youth" and the formation of the Wave 1 and Wave 4 Cohorts. Dataset 0001 (DS0001) contains the data from the Public-Use Master Linkage File (PUF-MLF). This file contains 30 variables and 67,276 cases. The file provides a master list of every person's unique identification number and what type of respondent they were in each wave for data that are available in the Public-Use Files and Special Collection Public-Use Files. Dataset 0002 (DS0002) contains the data from the Restricted-Use Master Linkage File (RUF-MLF). This file contains 93 variables and 67,276 cases. The file provides a master list of every person's unique identification number and what type of respondent they were in each wave for data that are available in the restricted-Use Files, Special Collection Restricted-Use Files, and Biomarker Restricted-Use Files.

PATH 研究（PATH Study）始于 2011 年，旨在为美国食品药品监督管理局（Food and Drug Administration，简称 FDA）依据《家庭吸烟预防与烟草控制法案》（Family Smoking Prevention and Tobacco Control Act，简称 TCA）所开展的监管活动提供信息支持。PATH 研究是由美国药物滥用研究所（National Institute on Drug Abuse，简称 NIDA）、美国国立卫生研究院（National Institutes of Health，简称 NIH）以及食品药品监督管理局下属的烟草产品中心（Center for Tobacco Products，简称 CTP）共同发起的合作项目。研究通过对美国 15 万多个邮寄地址的抽样，构建了一个全国范围内的烟草使用者及非使用者样本库。构成该研究首次（基线）数据收集波次，即 Wave 1 的，共有 45,971 名成年人和青少年。这 45,971 名成年人和青少年，连同 Wave 1 中的 7,207 名“影子青少年”（9 至 11 岁的青少年样本）共同构成了 53,178 名参与者的 Wave 1 群体。参与者被要求在每个后续波次中完成一次访谈。在当前数据收集波次达到 18 岁的青少年被视为“成年化青少年”，并受邀完成成人访谈。此外，“影子青少年”在 12 岁时被认定为“成年化青少年”，并在获得家长同意后完成访谈。在 Wave 4 中，从 Wave 4 当时的民用、非机构化人群中随机选取了 14,098 名成年人、青少年和 10 至 11 岁的“影子青少年”作为样本。这些样本来自未在 Wave 1 中被选中的居住地址，并采用与家庭内抽样程序相似的抽样方法进行招募。这一“补充样本”与 Wave 1 群体中 Wave 4 当时的民用、非机构化成年人和青少年受访者合并，总计 52,731 名参与者，构成了 Wave 4 群体。请参阅《受限使用文件用户指南》，以获取有关被指定为“影子青少年”的儿童以及 Wave 1 和 Wave 4 群体形成过程的更多详细信息。数据集 0001（DS0001）包含公共使用主链接文件（Public-Use Master Linkage File，简称 PUF-MLF）中的数据。该文件包含 30 个变量和 67,276 个案例，提供了每个人员的唯一识别号码以及在每个波次中他们作为受访者的类型，这些数据均可在公共使用文件和特别收集公共使用文件中找到。数据集 0002（DS0002）包含受限使用主链接文件（Restricted-Use Master Linkage File，简称 RUF-MLF）中的数据。该文件包含 93 个变量和 67,276 个案例，提供了每个人员的唯一识别号码以及在每个波次中他们作为受访者的类型，这些数据可在受限使用文件、特别收集受限使用文件和生物标志物受限使用文件中找到。
